TO ALLA WHOM IT yMAY CONCERN:

` Be it known that I, ERASTUS BUCK, of Vincennes, in the county of Knox,and State of Indiana, have invented certain new and useful Improvementsin Belt-Shippers ;A and I do hereby decla-re that the following is afull, clear, and-exact description thereof, reference being had to theaccompanying drawings, .and to theletters of reference marked theren,which form a part of this specification, in which- Figure 1 represents aplan or top view of a series of pulleys and belts, with my improvementapplied thereto. Figure 2, a plan or topl View of the same, and Figure 3a view of the shipper detached. The object of my invention is to providea convenient device for shipping belts, by the use of which the wear andrattling of the loose pulley upon the shaft will be obviated, andthebelt pressed towards the surface of the pulley in the operation,instead of being lifted from it; as is ordinarily the case to 4which endmy improvements consist in mounting the loose pulley of the primaryshaft, fromwhich power is to be communicated, upon a stationary sleeve,which encircles the said shaft, so as to prevent wear or rattling of theloose pulley upon the shaft, when thebelt is shifted to the fixedpulley, and providing the shipper, which shifts the belt, with inclinedarms furnished with friction-rollers, together with a projection, whichactua'tesa pivoted lever, by means of which the loose pulley is pressedagainst the fixed one, while the belt is being` shifted.

In the accompanying drawings, which'show a convenient arrangement ofparts for carryimg out the objects of my invention, A represents theshaft of the prime mover, which is rotated by the crank A', and B themain or line-shaft, from which power is to be communicated to a`counter-shaft, F. The main shaft C is provided with a pulley, C', whichcarries a belt, B', passing around a pulley, B, on the shaft A, fromwhich it is driven. The shaft C passes through a sleeve, D, secured tothe beam K', upon which sleeve a loose pulley, D', is mounted. A xedpulley,-E, is secured upon the shaft C, adjoining the loose pulley D',over which' a belt, E', passes, to drive the counter-shaft-F, by meansof a fixed pulley, F2, secured upon it. The counter-shaft F likewisecarries a loose pulley, F1. The belt E' is shifted from the fastto theloose pulleys, and, vz'ce versa., by means of the shipper II, whichslit' Vis in the beams K K', in which the shafts have their bearings.Theeshipper H is prol-vided with arms I,.bet\\een which the belt Epasses, and by which it is shifted. The arms I have friction-rollers I'upon them, and are set at an angle, converging towards each other, whenthe shipper passes within the belts, or diverging when it is without. Bythis arrangement of the arms, the bolt is pressed towards the surfaceofthe pulley when shifted, insteadof 'being drawn from it, as isordinarily tho case. A bent lever, G, is pivoted to the bestial one endof which is forked, to partially embrace the sleeve D adjacent to theloose pulley D': A projection, 7L, upon the side of the shipper Il,bears against the opposite end ofthe le'ver G, and thereby presses thepulley D' against the pulley E, when the belt is shifted from the formerVto the latter.

When thc shipper is moved, to transfer thc belt from the looseto thefast pulleys, thc projection h, striking against the end of the lever G,causes its opposite `end to prcss,the loose pulley D against the pulleyE, the i friction thereby produced causing the pulley D to revolve untilthe bolt has passed from it, when it remains stationary upon the sleeveD, and wear or rattlingiis obviated. The inclined position of thearms Icauses the belt to bc pressed up to the surface ofthe pulley while beingshifted.

What I cla-iin, and desire to secure by Letters Patent, is- Thecombination of the shipper II, pivoted lever G, und pulleys D' E, whenarranged and operating substantially as described.

In testimony that I claim the foregoing as my own, I ailix my signaturein presence of two witnesses.
